While reinforced concrete column–steel beam (RCS) joints are well-studied, the seismic performance of RCS frames incorporating floor slabs remains inadequately explored. This study extends previous experimental findings, developing and validating …

This study presents an innovative approach to predicting the compressive strength (CS) of recycled rubberized concrete (RC) using advanced hybrid machine learning (ML) algorithms. The integration of recycled rubber in concrete offers significant …

The incorporation of high-titanium slag may reduce the crack resistance of concrete. To promote the recycling of industrial solid waste while maintaining structural integrity, this study investigates the use of high-titanium slag as a replacement …

Farmers working on steep terrain need comfortable tools to improve their working conditions. Olive harvesting, which uses long unbalanced tools for reaching high branches, causes back pain. The posture of farmers, during harvesting operations, has …

Self-healing concrete is a cement-based substance that can mend itself from a hairline crack. This experiment examines the effectiveness of the gram-positive cell bacteria Bacillus cereus on the self-healing characteristics of steel-slag …

Steel fibers are added to concrete to enhance the shear strength of reinforced concrete beams and improve the post-cracking tensile strength of the material. However, creating an accurate simulation model to estimate the shear strength of …

This study explores the structural behavior of axially loaded reinforced concrete (RC) walls with openings strengthened using glass fiber (GF) or welded wire mesh (WWM) reinforced engineered cementitious composites (ECC). Eleven instrumented …

Multi-degree of freedom (DOF) robotic systems, particularly those with seven or more DOFs similar to the human arm, have the potential to significantly expand the functional range and versatility of robotic manipulators. The spherical gear …

Based on the age-adjusted effective modulus method, this paper proposes a set of closed-form equations to estimate the prestress loss in prestressed composite concrete girders made up of a concrete girder and a cast-in-situ concrete deck slab with …

To study the uniaxial dynamic tensile constitutive model of concrete under freeze–thaw conditions, the temperature field of concrete is modeled using finite element analysis software. The results are then imported into the thermal stress field as …

The large-scale application of high-performance fly ash based ceramsite is an effective way to achieve high-value utilization of solid waste such as fly ash. This study investigates high-strength fly ash ceramsite lightweight aggregate concrete …

Tunnel linings are critical components of underground infrastructure but are prone to cracking under complex, nonuniform loads. This study develops a nonlinear dual-parameter bond-based peridynamic (DB–PD) model to simulate crack initiation and …

This study proposes an innovative and practical retrofitting method for reinforced concrete (RC) roof T-joints with substandard structural details. Retrofitting was performed by assembling steel plates with threaded rods on the roof T-joints …
